Eco-Friendly Cruise Ship Design Includes Vertical Farms, Solar Sails, and a "Plant Kingdom"

If you want to reduce the environmental impact of your next vacation, you could do better than boarding a cruise ship. Luxury liners consume tons of fuel and produce even more sewage that is often dumped directly into the ocean. But cruises don’t have to be disastrous for the Earth by design: As inhabitat reports, the newly-designed Ecoship aims to be the most eco-friendly cruise ship on the seas.

The futuristic vessel was envisioned by the firm Oliver Design for the Japanese humanitarian organization Peace Boat. For decades, Peace Boat has been spreading its message of global social change through “peace voyages” that sail around the world. The Ecoship will embody this mission by being kinder to the environment than conventional cruise ships. Ten photovoltaic solar sails extend from the deck like giant fins, collecting clean energy to supplement the hybrid engine. Retractable wind generators harvest energy as well.

According to Oliver Design, the Ecoship will produce 30 percent less carbon dioxide than modern cruise ships. The vessel’s electrical system has also been updated with both the solar sails and kinetic floors onboard providing power. The biggest change comes in the sewage operations: Both the waste and water will be fed through a closed loop, which means that whatever’s produced is filtered and recycled again and again.

As these features are working behind the scenes, passengers will get to see some Earth-friendly amenities up close. A “plant kingdom” that covers five decks will consume surplus waste, water, and carbon dioxide produced by the ship, while vertical farms will be used to grow vegetables for meals.

When the Ecoship sets sail in 2020, it will continue to spread awareness of the changing climate that inspired its design. Oliver Design writes on its webpage, “The organization [Peace Boat] wants the Ecoship to be a turning point for the shipping industry and a flagship for raising awareness on climate change. As well as hosting Peace Boat’s voyages throughout the world, the ship will be used to stage exhibitions on green technology at the 100 ports where it is expected to dock each year.” You can check out the concept art for the project in the video below.

Looking for something to do this weekend that's both outdoorsy and free? To kick off National Park Week, you can visit any one of the National Park Service's more than 400 parks on April 21, 2018 for free.

While the majority of the NPS's parks are free year-round, they'll be waiving admission fees to the more than 100 parks that normally require an entrance fee. Which means that you can pay a visit to the Grand Canyon, Death Valley, Yosemite, or Yellowstone National Parks without reaching for your wallet. The timing couldn't be better, as many of the country's most popular parks will be increasing their entrance fees beginning in June.

The National Park Service, which celebrated its 100th birthday in 2016, maintains 417 designated NPS areas that span more than 84 million acres across every state, plus Washington, D.C., American Samoa, Guam, Puerto Rico, and the Virgin Islands.

How the Planet Has Changed Since the First Earth Day in 1970

The first Earth Day in 1970 was celebrated with protests, nature walks, concerts, and other activities meant to spark interest and engagement in the planet's well-being. Since then, April 22 has been a day to reflect on our impact on the environment, on broad and individual scales. So just how much has the Earth changed since the first Earth Day 48 years ago? According to this video from the American Museum of Natural History, it's changed a lot, and not for the better.

The world's population has doubled since 1970, from 3.7 billion then to over 7 billion today. While there are more people consuming resources, more resources are also being consumed per person. On average, we're each burning 37 percent more fossil fuel than we were in 1970, eating 60 percent more meat, and taking 495 percent more plane trips. All that consumption adds up to 1.2 trillion tons of CO2 emitted in the past five decades, which contributed to ocean waters warming 1°F and sea levels rising more than 5 inches.

Those numbers look pretty grim, but it isn't all bad news: Humans have also made significant strides toward protecting the environment in that same period, including passing the Endangered Species Act, designating protected marine areas, and signing international agreements to reduce greenhouse gas emissions across the globe.

People are also more aware of what can be done on a personal level to reduce their carbon footprint. For tips on how to be greener this Earth Day, check out our list of eco-friendly habits.
